SUSY designed broken PT-symmetric optical filters
Ugo Tricoli, Jean-Claude Krapez
We apply the supersymmetric Darboux transformation to the optical Helmoltz wave equation to generate analytically complex-valued PT-symmetric potentials (physically a graded refrac…

Multipurpose S-shaped solvable profiles of the refractive index: application to modeling of antireflection layers and quasi-crystals
J. -C. Krapez
A class of four-parameter solvable profiles of the electromagnetic admittance has recently been discovered by applying the newly developed Property & Field Darboux Transformation m…

Sequences of Exact Analytical Solutions for Plane-Waves in Graded Media
Jean-Claude Krapez
We present a new method for building sequences of solvable profiles of the electromagnetic (EM) admittance in lossless isotropic materials with 1D graded permittivity and permeabil…
